Execute reviewed testimonial tasks

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations cover safety (destructive, non-idempotent, open-world), but the description adds genuinely new behavioral detail beyond them: prevalidation of all tasks, exact-hash verification before the first request, and precise failure semantics (stop on first failure, no retries, rollback, or implicit continuation). This is high-value disclosure an agent could not get from the annotations alone.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two dense sentences with the confirmed-batch scope front-loaded and failure behavior trailing. Every clause carries information, though the telegraphic abbreviations ('known results/failed index/unattempted indices') are slightly compressed for readability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a destructive batch tool with no output schema, the description covers failure return shape (known results, failed index, unattempted indices) and the hash-precondition workflow, complementing the annotations. Prerequisite tooling and success-return shape are the only mild gaps.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so tasks, account, confirm, and review_sha256 are already documented in the schema. The description reinforces ordering and the 1-20 bound and references the hash, but adds little meaning beyond structured fields. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a specific verb+resource: executing a confirmed batch of 1-20 ordered text/video/email testimonial tasks. It distinguishes this from the preview step via 'Confirmed' and the hash check, though it does not explicitly name the sibling preview_testimonial_batch. An agent can identify the operation, but sibling differentiation is only implied.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied rather than stated: 'Confirmed' plus 'verify exact hash before first request' hints at the preview-then-execute workflow, but no sibling is named and there is no explicit when-to-use vs when-not guidance. The reader must infer that preview_testimonial_batch is the prerequisite.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
